ROTARY EXPLOSlVE-MOTO R.

SPECIFICATION forming part of Letters Patent No. 660,129, dated October23, 1900.

Application filed November 29, 1899. Serial No. '738,693- (No model.)

To @ZZ whom t may concern:

Be it known that l, PHILANDER H. STAND- ISH, a citizen of the UnitedStates of America, and a resident of Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Gas- Motors, of which the following is a specifica'-tion.

'lhis invention relates to gas-motors; and it consists in the newconstructions and combinations of mechanism,substantiallyas hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Sheet l,

Figure l, is a side elevation, parl ly in section, f

of my new gas-motor. Sheet 2, Fig. 2, is a transverse vertical sectionon line 2 2 on Fig.` l looking from the left. Sheet 3, Fig. 3, is a topor plan view of the gas-motor.

A represents a circular casing, through the center of which isr placedthe shaft B, carrying the rotary piston O. Said casingis extended in itsupper part and contains the chambers for the valve and explosionpurposes. The casing may be made in two 0r more parts, being divided ason line A', Figs. l and 3.

In the side and circular walls of the casing are provided the spaces oa, in intercommunication, for containing Water, thus providing awaterjacket, surrounding the chambers and valve, through which a currentof water is forced for cooling purposes. The two parts of the casing aresecured together by means of bolts in the customary manner. The piston Ois eccentric in form and of less diameter than the chamber in which itrotates, and has one side extended in the form of an ellipse, whichimpinges against the circular sides of the chamber.

D is a reciprocatory bulkhead or resisting abutmen t,against which theexplosive force is exerted in opposition to the piston. It is segmentalin form and is journaled in a bearingcl in one side of the casing andhas play in a segmental cavity d in the upper side of thepiston-chamber. Said abutment D rides on the rounded surface of thepiston and is lifted by the elliptical extension as said pistonrevolves.

E is an explosion-chamber contained in the casing over thepiston-chamber at one side of the central line and is connectedtherewith by the inlet-port e. Above the explosionchamber is alsoprovided a straight chamber F. 'lhis chamberis closed by the cap-platef.

G is a vertically-reciprocatory Valve the head of which moves in theupper chamber F, while its foot closes and opens the port e.

In ythe side of the casing A and connected with the explosion-chamber isprovided the electric igniter, which consists of two electrodes I and J,inserted through aninsulatingplug H, fixed in the opening in the side ofthe casing. The upper electrode I is stationary. The lower one J isloosely held and has oscillaing movements imparted to it through themedium of the crank 7c, connected by rod Z with a lever L on the end ofrock-shaft K, journaled inbearings 1l t' on the side of the casing A.Said rock-shaft K derives motion by means of a depending arm m,contacting with and pushed by projecting incline M on the fly-wheel W.yS is a spring having one end fixed to the casing and the other attachedto the lever L, and which acts in opposition to said incline for keepingthe electrical circuit open, the incline acting to automatically closesaid circuit once in each revolution of the fly-Wheel.

For charging the explosion-chamber with gas a pipe P is inserted in theside of the casing and secured therein by bolts through its flange r andleadinginto the side of said chamber and having its outer end connectedwith a carbureter R. At one side of said pipe is provided a pum p-barrelQ,-having its piston connected by pitman Q With an eccentric Q2 on'thedriving-shaft B. vThe pipe P is divided by a cross-wall p over thecenter of said pump.

T is a suction-valve in the pipe at the side `of the partition-Wall pleading from the carburetor. U is a discharge-valve in pipe P at theopposite side of said partition-wall p. Through these valves the pumpdraws and forces the gas to the explosion-chamber.

U is a valve for closing the end of pipe P iu the explosion-chamber, itsstem being supported in a perforated sleeve u, secured in the pipe P byscrews s s. To the `inner end of the stem is attached a perforated headV. A spring t is placed on the stem between the sleeve and head, whichserves to keep the valve closed. The purpose of making the IOO sleeveand head perforated is to provide for the passage of gas.

For lubricating the interior a passage N is made through the casingleading into the valve-chamber F. A valve-box O is fixed in the side ofthe casing at the outer end of said passage, having a U-shaped passage,with a ball-valve n, controlled by a screw-plng n' in the box over thevalve. A pipe O' is attached to the top of box O for conveying alubricant from an oil-cup or other suitable source into said box. Anopening f1] is made in the side of the box O for the admission of air,which becomes carbureted as it mingles with: the lubricant. At theopposite side of the chamber F is also provided a passage c, leadinginto a second valve-chamber z', in which is also provided a ball-valvez2, which isV also controlled by a screw-plug .e3 in the cap-plate 2o f.From the bottom of said chamber e is made a narrow passage fr, leadinginto the cavity CZ. This passage is also controlled by a needle-pointedpin screwed into the top platef.

The workings of this motor are as follows: To start it, the fly-wheel isgiven a revolution. This carries the piston around one revolution. Atthe same time the pump Q will draw and force gas into theexplosion-chamber E. The igniter is also operated by the incline M onthe iiy-Wheel. Now an explosion takes place in chamber E. This liftsvalve G and opens port e, and the piston is acted upon. The explosionalso forces valve` U shut. The upward movement of valve G in its chamberF serves also to admit air and valve G returns after the explosion, itforcesthe air and lubricant that came in through passage N through thepassage a by lifting ballzz. This provides chambers ,a/ and F with moreair and lubricant.

Having described my invention, what I claim isl. The combination withthe Working cylinder and piston, of an explosion-chamber, a

chamber, a port connecting the cylinder and port connecting the cylinderand chamber, a valve for said port, a cnshioning-chamber above thevalve, a head on the valve-stem located in the cushioning-chamber andhaving a lower face exposed to the explosion-chamber, whereby theexplosions lift the valve, substantially as described.

2. In a gas-motor, the combination with the Working cylinder and piston,an explosionchamber, a valve for said port, a cushioningchamber abovethe valve, a head on the valvestem located in the cushioning-chamber and1 having a lower face exposed to the explosionchamber, and an igniterconnected with the explosion-chamber, and adapted to operatesubstantially as described.

3. In a gas-motor, in combination, a working cylinder and piston, an`explosion-chamber, a port connecting the cylinder and chamber, a valvefor said port, a cushioning-charm berabovc and for said valve, a pipeconnecting the explosion-chamber with a carbureter, valves in said pipe,and a pump connected with said pipe and having its piston opera tivelyconnected with the main shaft `for forcing carbureted air into theexplosion-chamber, substantially described.

4. In a gas-motor, the combination with the working cylinder and piston,an explosionchamber, a port connecting the cylinder and chamber, a valvefor said port, and a cushioning-cha1nber above the valve, and a head onthe valve-stem located in the cushioningchamber; of a lubricatorconsisting of a valvebox O attached to the side of the casing, a passageN connecting said valve-box with the cushioning-chamber F, avalve-chamber e", a passage .c connecting said chamber with chamber F,and controlled by valve z2, and a passage w connecting chamber with thecavity d', and. regulated by screwplug s3, substantially as described.
